ENVELOP-MAKING MACHINE.

To all whom it may concern:

Be it known thatI, PHILIP H. FARRELL, a citizen of the United States,and a resident of Flushing, in the county of Queens and State of NewYork, have invented certain new and useful Improvements in Envelo)-Making Machines, of which the following is a specification.

This invention relates to the cutting mechanism for a machine for makingenvelops, bags and the like. Its organization comprises a rotating drumwhich carries one or more cutters, for cutting a sheet of paper or othermaterial bearing on the drum, the said cutters being actuated by astationary cam.

To exemplify the invention it is shown with a complete envelop makingmachine.

In the accompanying drawings which exemplify the invention Figure l is apartial vertical section of the invention, as on a line at, 00 of Fig.2, Fig. 2 represents a plan View of Fig. 1, and partial section on theline 00, m. Fig. 2 shows a plan view of a blanking out drum. Fig. 3shows an enlarged portion of Fig. 1 containing the knife, Fig. A is aplan view of Fig. 3 with a portion of the frame of the machine, Fig. 5shows a partial end view and section of Fig. A on the line 00 00 Fig. 6is a side View of Fig. 4. Fig. 7 shows an enlarged plan view of themachine with the envelops in their different stages of manufacture.

A frame is represented at A with the sides A, A It supports a spool B,in the bear ings a, for a sheet of material, paper and the like C. Aroller D is journaled in the sides A, A of the said frame.

A rod E is held in the frame which supports a pair of loose sleeves E,that each have a groove 6. A rod E extends between the sides of the saidframe and carries the supports E for the creasing rollers E A pair ofhangers E extend from end of the supports E and encircle the rod E thebolts 6 clamping the hangers E in position.

A blanking out drum F is secured to a rotating shaft f, the ends ofwhich are car ried in bushings F, which with the ring cams F are clampedto the sides of the frame A, by means of the bolts P. On the extensionof the shaft f is secured the spur gear F Extending from the sides ofthe drum F are the journal bearings f which by means of the pins f carrythe cutter supports F, from which latter extend the cut- Specifieationof Letters Patent.

ters f. Guide lugs f extend from the cutter supports 7 and straddle thecams F Above the rotating blanking out drum F is journaled a creasingroller G on the shaft g, which has extending from its circumferentialsurface the dies 9, that crease the sheet of paper or other materialover the notches f in the surface of the drum F, the said notches beingarranged to engage with the dies 9. The shaft 9 carries the spur gear Gwhich meshes with the spur gear F A roller H is journaled in the sidesof the frame A, and below the same is journaled a gumming wheel H, whichrotates in a gum box H 011 the spindle it supported in bearings itextending from the sides of said box. The box is supported on a bracketH fastened to the lower plate A of the frame A. The spindle it carries asprocket chain wheel k which is connected by the chain 71. with asprocket chain wheel h on the shaft Z.

Across the width of the machine and se cured on shelves A" extendingtherefrom, is the shelf 1, that supports the aprons I and I A coverplate J is held over the said aprons, by means of the rod K. A pair offeeding rollers L and M are supported on the shafts Z, and m, the rollerM having the flanges 022-, so as not to bear on the portion of the paperwhich has been gummed, or on its longitudinal axial line. The shaft Z isjournaled in the bearings a and carries the spur gear 0, that mesheswith the pinion O, on the spindle O The pinion O meshes with the spurgear 0 carried on the shaft which latter is journaled in the bearings aOn the shaft 0 is fastened the supporting roller 0 and over the latteris journaled the gumming roller P on the spindle p, and has the slightprojection 79 extending longitudinally across its circumferentialsurface. Over the roller P is the gumming roller P, which is driven bythe projection 72 of the roller P. The roller 1? bears on the roller P,and the roller P bears on the roller P The roller P rotates in the gumbox P The spur gear 0 meshes with the pinion 0 carried on the spindle Oand the pinion O meshes with the spur gear 0 which is fastened on theshaft 0". The shaft 0 carries the cutting off drum Q, which has theslots Qlongitudinally across its circumferential surface. At the ends ofthe drum Q project the bearings Q for the spindles Q on which latter arecarried the knife frames R with the knives R. The

knife frames R have the lugs R which straddle the ring cam S, that hasthe arms S, and by means of which latter is fastened to the sides A ofthe frame A. On the shaft is also fastened the disk T, from which arejournaled on the spindles t the spur gears T, that mesh with the spursectors T the latter being journaled from the disk T on the spindles t.A pin It extends from the side A of the frame and is located in the pathof the sectors T On the spindles t of the spur gears T are fastened. thefolding blades T that are arranged to bear on the paper or othermaterial on the cutting off drum.

'A sector V is journaled on the pin V extending from the side A of theframe, and it has the teeth V that mesh with the teeth of the spur gearV The latter is fastened to the shaft V of the crank From the latterextends the arm V, that supports the holding blade V The sector V isarranged to engage with the cam WV on the shaft 0.

On the shaft Z is mounted the pulley L, and the sprocket chain wheel Lwhich latter is connected by the chain L to the chain wheel F on theshaft To operate the invention the machine is driven by means of thepulley L. The paper or other material on the spool B is led under theroller D, and from thence passes between the creasing rollers E andloose sleeves E, by virtue of which it receives two creases thatdetermine the width of the envelop to be produced. The paper, &c., thenpasses over the blanking out drum F, against which it is tightly held bymeans of the creasing roller G, the dies 9 of which form creases 21therein to mark the length of the envelops. WVhile the paper is on thedrum F the cutters f blank out the paper to the proper form for theenvelop, as shown at 22 the drum rotating and the cutters actuated byreason of the lugs f engagingwith the ring cams F The paper is next ledunder the roller H, when the gumming wheel H gums one edge thereof. Thepaper then passes between the aprons I I and the cover plate J. Thefolders I and I of the said aprons bend the paper at the longitudinalcreases, and the folders I and I fold the paper down to form the envelopof the proper width. The folder I being a little in advance of thefolder I, the folded edge made by the folder I is under the edge of thepaper folded by the folder I. The folded paper now passes between thefeeding rollers L and M, gripping the paper between its longitudinalaxial line and the longitudinal edges, so as not to pass over a threethicknesses of paper, and not to spread the gum. The paper then passesbetween the supporting roller 0 and the gmnming roller P, which are soproportioned that the projection 72 gums the paper across its surface,so as to be enabled to gum and close one end of the finished envelop.The proj ection p is gummed by means of the rollers P, P, P and gum potP". Now the paper passes on to the cutting off drum Q where it is firstcut by the knives R, the latter being actuated while the drum isrotating, by reason of the engagement of the lugs R with the ring cam S,which move the knives through the material and slots on the said cuttingoff drum and out again. The cut end of the material is then held inposition by means of the holding blade V, which has a movement to andfrom the surface of the drum Q. Before the blade V leaves the materialon the drum Q the folding blade T starts to turn over and fold the end.of the material to form the closed end of the envelop, securing theportion that has been gummed across its face in place. After the envelopis formed and folded as just described, the holder V moves away from thedrum, and folder T turns to its original position shown in the drawingsand the envelop is fed forward and cut off by one of the knives.

Having described my invention, I claim:

1. In an envelop making machine the combination of a blanking-out drum,means to feed a sheet of material to the drum, means to rotate the drum,a cutter journaled with 'the drum and arranged to operate through anopening in the surface of the drum, a ring cam adjacent to the drum, andlugs extending from the cutter straddling the ring cam.

2. In an envelop making machine the combination of a blanking out drum,having openings in its circumferential surface, means to feed a sheet ofmaterial to the drum, means to rotate the drum, lugs extending from thedrum adjacent to said openings, cutter supports pivoted in the lugs,cutters extending from said supports, lugs on the supports, a ring camin the machine straddled by the latter lugs so that they will follow thepath of said ring cam during the rotation of the drum.
